ABSTRACT:
An improved method for modifying the surface of an ocular implant material by the gamma or electron beam irradiation induced chemical graft coating thereon of a monomer comprising N-vinly-pyrrolidone, 2-hydroxyethylmethacrylate or a mixture of the two to form a hydrophilic graft polymer coating, the improvement comprising pre-soaking the ocular implant material in a monomer or a solution comprising a monomer prior to conducting the gamma- or electron beam-irradiation induced graft polymerization in a second solution of a monomer.
